Title: Process of and apparatus for improving the thermal economy of adsorption processes performed by the aid of bodies of large superficial area and with expulsion of the adsorbed substances by means of scavenging media
IPC: B01D53/04
Filed: 1930-10-29
Abstract: <PICT:0348006/III/1> In the recovery of gases or vapours from solid adsorbents by treatment with a flushing medium such as steam, the vapours issuing from the apparatus are passed through a heat accumulator. The heat thus recovered may be used for any purpose, for example for heating the gas which is subsequently passed through the adsorbent to dry it.  In the apparatus shown in the Figure, steam is supplied at a and after passing through the adsorbent b is led through the accumulator B.  Condensate is withdrawn at f and the remaining steam and vapour passes out at e.  Subsequently the drying medium is admitted at a<1> and passed through the apparatus in the reverse direction.  The heat accumulator is preferably composed of a number of separate units to prevent temperature equalization within it, or it may be placed within the adsorption chamber itself.  The heat-storing medium may be either solid or liquid, e.g. the condensate obtained from the regeneration of the adsorbent may itself be used for this purpose. Supplementary heating and cooling devices and heat-recovery devices such as compression evaporators may be used in conjunction with the accumulator.

Title: Apparatus for making calculations relating to the loading of beams and ships
IPC: G06G1/00
Filed: 1948-12-16
Abstract: 669,563. Calculating-apparatus. MURRAY, J. M. Dec. 12, 1949 [Dec. 16, 1948], No. 32585/48. Class 106 (i). An apparatus for adding and subtracting moments of load in a ship or in a beam about any predetermined point in order to determine the resulting bending moment at that point or, if the section modulus is known, the stress, comprises several manually-operable setting means associated with scales of loads, each calibrated for a chosen point on the ship or beam, the setting means directly setting a single member operating indicating means from which the said bending moment or stress may be read. Several knobs l ase associated with scales r. The scales are calibrated according to loads and in such a way that the setting of a knob according to the corresponding scale moves a band or chain b by an amount proportional to the moment about the point considered. The band or chain passes round idler wheels d and wheels or sprockets a coupled to the knobs, when the latter are depressed against springs p, by the engagement of a pin o on the wheel with the teeth of a spur wheel n fast to the knob. The resultant moment is indicated by a pointer c carried by the band or chain which is tensioned by a sprung pulley or sprocket e. The wheels are mounted between a base h and a cover j. Subtraction of moments may be effected by reversely setting the knobs or by passing the band or chain round appropriate wheels in a different direction. The pointer c may be coupled to the wheels a by an additional chain passing round wheels of one size, at least one of which is fast with a wheel of different size rotated by the band or chain b. According to the Provisional Specification, the band or chain may be replaced by a toothed rack. A duplicate apparatus having a knob l<SP>1</SP> and pointer c<SP>1</SP> may be used to calculate the draught of a ship. The pointer c, c<SP>1</SP> may read against a curve representing the moments of buoyancy of a ship for different draughts. Curves drawn parallel to, and at unit distances from, this curve facilitate the reading of the difference between the moment of buoyancy for the appropriate draught (indicated by the pointer c<SP>1</SP>) and the resultant moment of load (indicated by the pointer c), which difference is equal to the bending moment at the section considered. Additional curves to enable the trim of a ship to be found may be provided.

Title: Improvements relating to sliver coilers
IPC: B65H54/80
Filed: 1956-10-26
Abstract: 845,893. Coiling textile sliver. McDONOUGH POWER EQUIPMENT Inc. Oct. 26, 1956 [Oct. 28, 1955], No. 32638/56. Class 120(3). A sliver-coiler comprises a vertical column 12, carrying at its upper and lower ends, supports 54, Fig. 1 and 86, Fig. 4 on which are respectively mounted to rotate, a coiler-tube gear 42 and a can-table 96, both supports being separately angularly adjustable in a horizontal plane relatively to the column. There is provision, too, for adjusting the position of the cantable relative to the column. Each support is carried by a plug 58 or 88 rotatable in the column and fixable by set screws 60, 90. The column houses a shaft 18 driven by bevel gears from a horizontal shaft which enters the column centrally from left or right: the shaft has upper and lower bevels 40, 44 respectively driving the coiler tube gear and the can table. In the former case the bevel 40 meshes with teeth 56 Fig. 3 (not shown) on the coiler gear which has spaced rollers 80 running on an inclined surface of the support 54; a track for engaging rollers 74 on a stationary cover 68; and a support 62 for a coiler-tube 64 communicating with an aperture in the gear. In the case of the can table 96, the drive from the bevel gear 44 is through a worm shaft 48, the worm engaging a toothed wheel 95 by which the can-table is carried. The gear wheel 95 is carried by a bearing 122 in a member 114 which is bolted to the floor of a gear-guard 94 which is itself bolted to the support 86. The guard has spaced rollers 99 on which the can table can run; a bearing for the worm shaft; and a wide central aperture for the shaft 124 of the gear wheel which can be changed to permit different speeds of coiling. To allow for the transmission of the drive whatever the diameter of the gear-wheel employed, the worm shaft leaves the plug 88 through an arcuate slot and the position of the worm is adjustable on its shaft. The bolts by which the guard 94 is secured to the support 86 and the member 114 to the guard pass through slots to permit the can table to be radially adjusted with respect to the column to allow cans of varying sizes to be used. In an alternative form Fig. 9, the worm is replaced by a chain drive, the drive being from a sprocket 174 driven from gearing which is interchangeable to provide various speeds of drive. Slots 182, 184, 186 in the guard 180 each have two arms to permit the apparatus to be adjusted for cans of different sizes in the case of either a left or righthand power take-off drive. Specification 845,894 is referred to.

Abstract: 1525825 Automatic control of engine exhaust NISSAN MOTOR CO Ltd 5 Aug 1976 [5 Aug 1975] 32648/76 Heading G3R In a system controlling the fuel/air ratio fed to an I.C. engine 10 in response to an exhaust composition sensor 12 and using an integrating controller 20, means 30 is provided for detecting at least one transient engine condition (e.g. acceleration, deceleration) and for disconnecting the exhaust sensor 12 from the controller 20 during that con-  dition, a predetermined D.C. voltage being then applied to the device 11 which controls the engine fuel/air supply. Fig. 1 shows an arrangement using electronic switches 24, 28 which are normally as shown so that s two-valued exhaust composition error signal from comparator 14 is integrated by amplifier 23 and then summed, by amplifier 22, with the output of proportional controller 18. When detector 30, which may be a throttle position sensor, detects a condition requiring an unusual fuel mixture, the switches are actuated to short out integrating capacitor 26 and to supply a pre-set voltage from resistor 32 to the amplifier 23. A corresponding D.C. voltage appears at the control input of the fuel injector or carburetter 11. The pre-set voltage may be chosen close to the comparator reference voltage to smooth the changeover when the engine returns to a cruise condition. Alternative arrangements are described (i) to eliminate amplifier 23 Fig. 2 (not shown); (ii) detecting deceleration by integrating the pulses fed to a fuel injector Fig. 5 (not shown); and (iii) with separate detection of acceleration and deceleration to provide corresponding different pre-set voltages at the input of amplifier 23 Fig. 3 (not shown).

Abstract: 893,648. Feeding webs. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 17, 1958 [Oct. 18, 1957], No. 32654/57. Class 100(1) [Also in Groups XIII and XL(b)] An apparatus for the treatment or treatment and analysis of material in the form of a strip of absorbent paper or like absorbent material in chromatography includes a pair of endless feed belts, means supporting the belts for relative movement in separate paths of travel, the belts being so relatively disposed and so driven by driving means as to move at the same speed in a common longitudinal direction during portions of their travel in which they lie parallel with one another and in close proximity to engage between them a part of the width of a strip of material to be treated leaving a substantial portion of the width exposed and thus move the strip in the longitudinal direction, and means for treating the exposed width of the strip. As shown, a strip 3, Fig. 3, of paper or other absorbent paper for use in producing chromatograms is fed manually or otherwise between endless feed belts 16, 17 and 18, 19 which grip the strip 3 at its edges only. The belts may be of stainless steel, nylon, or woven glass fibre. The belts 16, 18 pass around rollers 90, 23, 25, 28 and 41, Fig. 1, while the belts 17, 19 pass around rollers 91, 24, 26, 28 and 42. The roller 28, partly immersed in a bath 30, applies treatment liquid to the strip, the amount of liquid applied to the strip being variable by varying the speed of the roller 28. The belts then pass into a treatment chamber 5, Fig. 4, around a roller 57. The chamber has six vertical compartments 44, 45, 46, 47, 48 and 49 formed by partition walls 50, the strip being fed through the compartments in succession by the belts 16, 17, 18, 19 guided by rollers 56, 57 which may be covered with synthetic plastic material. The belts and strip pass through rollers 61, 62 whereupon the belts 16, 18 pass upwardly, the belts 17, 19 pass to the left, and the strip downwardly to an inspection zone. In the inspection zone, the strips are illuminated on one side while the other side is scanned, e.g. by a photo-electric cell to measure the optical density of markings on the strip, the output being fed to a recording apparatus. The rollers 61, 63 and 23, 24 are driven in synchronizm to ensure constant speed of the strip through the apparatus.

Abstract: 941,512. Two-part couplings. ELECTRONIC ASSOCIATES Inc. Aug. 24, 1962 [Nov. 15, 1961], No. 32704/62. Heading H2E. A coaxial plug for a computer patchboard has the central contact surrounded by a spring- loaded sleeve which is retracted when connection is made. As shown, Fig. 1, an insulating body 24 carries a central contact 42 and a second contact 44 provided with cam surfaces 46, to which contacts are respectively connected to the inner and outer conductors 48, 50 of a coaxial cable. The central contact is surrounded by a spring-loaded sleeve 15 which is provided with metallic salts 20. When the plug is inserted into an aperture 12 in a panel 10, the balls prevent the insertion of the sleeve until the centre contact has been pushed forwards against the bias of the spring 49 to make contact with the spring contact 43. The balls descend the cam surfaces 46 and the sleeve enters the aperture as far as the stop 16. On releasing the insertion pressure the body is biased away from the panel causing the balls 20 to ride up the cam surfaces and press against the inside surface of the aperture 12, thus retaining the plug in position and also completing connection of the braid of the cable to the panel 10. In a modification, Fig. 3 (not shown), the ball bearings are replaced by S- shaped spring portions which are formed as part of the sleeve. The tip of the first contact in either embodiment may consist of a nylon cone to prevent accidental short circuiting of the contact with the panel, and a rubber or plastic sleeve 56 may cover the cable entry end of the plug.
